Head scratching time


Baccus

Recommended Posts

On the weekend I decided to try siphoning out some of the mulm out of my native tank, since I am sick of every time I do anything in the tank it turns into a rather dark murk.

So I blissfully used a length of air hose tube to use as the siphon and watched carefully to ensure no shrimp or new born spotted blue eyes went for a ride into the bucket of future doom.

Now this morning after adding new green leaves to the tank yesterday, I discovered new born native shrimp hanging out on the green leaves. At first I only spied one because it moved when I shone a torch in the tank before the lights where due to come on.

So here is the head scratching moment, how on earth do I make sure that none of these insy little shrimplets are in the bucket of gunk? They are so small that they will go through almost any net, and any net fine enough to trap the shrimplets will also trap the gunk, which defeats the whole purpose.

I could just leave them in the buckets to grow up but between the other half whinging every time he see's a bucket of water laying about in the shed, and the dog thinking all water is for him to drink, as well as a cat addicted to fish water and the prospect of a million mozzies breeding in the water I am at a loss.

Any how see if you can spot the shrimplets. There is at least two in all the pictures.

Hint for the above.....look near the small rams horn snail

They look soooo tiny, very cool! I have no idea how you syphon without accidentally sucking any up cause if you put anything over the end of the hose then it won't pick up the mulm either, definitely a head scratcher! :confused:

I would use the same method I use for checking duckweed for shrimp.

Have 3 containers, 2 small and one large.

In one small container catch out a bunch of mulm and dilute it, check for shrimp and if there are any syringe them into the other small container and then dump the waste into the large bucket.

A slightly older shrimplet but still tiny.

Good to see he's eating well :)

Insanely small, the tank is pretty thick with the little guys, but the best time to spot them is with a torch after the tank light has been out.

Yeah. I would dilute it with clearer tank water in a shallow wide container and inspect it under strong light for shrimplets.

Any idea which natives the babies might be?

My main guess would be the Blackmore shrimp since they have bred previously, the next two culprits are the Darwin Red Nose since I have seen berried females or the chameleons who I almost never see.

Finally managed to get a pretty clear (in focus) picture of a native shrimplet that is at most 1 day old.

I hate to think how many would be disappearing up the filter if it was well wrapped in plant life that is supposed to be floating in the tank.

If I can locate him again and manage to get the camera to focus again I will try to get a shot with a ruler in the photo too, its so small I think he would nearly be measured in mircons rather than millimetres.

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.

      Hello! I have a tank that currently does not contain shrimp, but does contain neon tetras which I am currently treating for Ich, as well as some bladder snails. Shrimp will be a later addition, likely cherry shrimp but I'm still doing research just to be sure. Initially I'd intended to buy some sort of Ich-fighting product that contains malachite green after doing a decent bit of research on it, most of which indicated that it should be shrimp-safe so I'd be good if I ever needed to use it again once shrimp were actually introduced (though I should note I'm aware shrimp can't get Ich, I'm more wondering in case the tetras could get Ich again, or something else that responds to similar medication). I ended up not being able to find any MG-containing products without either having to travel quite far or wait multiple days for delivery (which I was worried could lead the Ich to be fatal), and ended up picking up 'Top Fin Ick Remedy', a product that contains gentian violet which is a triarylmethane dye like malachite green. The bottle has two slightly differently worded warnings about its use with invertebrates ("not recommended for" and "not safe for" respectively), but when I'd been researching malachite green, I'd also heard of products that contain MG but not any other ingredients that would be harmful to inverts still being branded with warnings that they could be harmful, just as a "just-in-case" since the manufacturer didn't test it on any inverts, and I'm wondering if maybe it could be a similar situation here. I'm having a very very hard time finding information about gentian violet's use in fishkeeping at all though, it seems currently extremely uncommon. What I will say though is that I'm on day 2 of treating my tetras with it, and the bladder snails seem just fine -- in fact today I noticed what looked to be a bladder snail that appeared to be newly hatched (because of its size) that I hadn't seen before that was zipping around the tank without issue. But obviously, shrimp are not snails, and bladder snails are also notoriously hardy little guys, so what I'm seeing right now could easily be totally inapplicable to cherry shrimp. It might even be inapplicable to other species of snails, for all I know. Has anyone else here ever used anything that contains gentian violet in a tank that actually does contain shrimp? Were they okay, or should I make sure to not use it once shrimp are added?
